This approach iteratively distributes candies to people in a sequence, considering one cycle at a time until all candies are allocated.
Time Complexity: O(sqrt(2 * candies)). This is because the linear sum of the sequence continues until all candies are exhausted, which resembles the behavior of an arithmetic series.
Space Complexity: O(num_people), since we maintain an array to store the number of candies for each person.

5 while (candies > 0) {

7 candies -= amount;
8 amount++;

14 int candies = 7, num_people = 4;
15 int result[4] = {0};

The C solution utilizes a simple while loop for the distribution of candies. It tracks how many candies to give based on a running total. The modulo operation (%num_people) ensures allocation is cycled through the people repeatedly until candies run out.
Using a mathematical approach, calculate full rounds of distribution first to optimize the solution as opposed to simulating step-by-step distribution.
Time Complexity: O(sqrt(2 * candies)) due to converging arithmetic series.
Space Complexity: O(num_people).

The C# code leverages reflective calculation of sequential candy distributions to cover full rounds as fast as possible with minimal additional computations upon iteration.
